JIS Z 3147:2017

JIS Z 3147:2017 specifies the method of high-speed rotating bar bending fatigue testing at room temperature and at a frequency of over 5 000 cycles/min up to and including 8 000 cycles/min (hereafter referred to as high-speed test) for obtaining the fatigue life in the high cycle range, in which the number of cycles is over 10(7) up to and including 10(9), for the base material and junction of structural aluminium alloys and structural magnesium alloys used for rolling stock, marine vessels, automobiles, etc.
